Biometric verification is a security process that uses unique physical characteristics to confirm a person's identity. Common biometric traits include fingerprints, facial recognition, iris patterns, and voice recognition. This technology is often used in devices like smartphones and security systems to ensure that only authorized users can access sensitive information or areas. The main advantage of biometric verification is its accuracy and convenience. Unlike passwords or PINs, which can be forgotten or stolen, biometric traits are inherently unique to each individual. As a result, this method provides a higher level of security and can streamline the authentication process in various applications, from banking to border control.
